Referring now to the drawings in detail, a truck frame of known general design is designatedas and the journal ,boxes thereof as B, these latter also being of a known general design. in other words, it is well known to those skilledin the art that a so-calledselfe lubricating journalbox usually is. inclusive.

of a al port on f l t i ly lar iew width and height within whichis contained a bearing against which the axle journal seats, and that the box is enlargedat its front; andrear to accommodate. an oil elevat; ing paddle and an oil, obturatingring, respectiyely, which. are. mounted on the. axle for.

ing designed; to prevent escape of oil from the box through the opening in the rear therepaddle being esigned to, elevate oil from thebotton of the box to the hearin The present box is of this general; design, and,

since such design is well knowin it has been deemed unnecessary to illustrate. any more of; thedetailstheneof than are necessary for.

a clear; understanding of the invention, Ac-

I cordingly,th'e box B is shown merely as com.-

In combining the box B; in a one-plece stnucturewith the frame the end portion at least of the frame formed of a, width to extend between the, front and rear enlargements 1 3 and 1,4 and to. join directly with the ccntralbox portion 10, whereby, saidenlarged portions l and 14lmay extend;

in the manner stated, ample space is afforded to enable the box and particularly; the parts 10, 13 and 14 thereof to be. formed. of; de sired maximum. size.

The frame A is .illusurated inthe, present instance as of hollow construction and: inclu sive at its ends of top and bottom, walls 15 j and; 16, respectively joined by sidewalls 17,

of through, which the. axle extends, and the.

frame against being broken therefrom by force exterted against the box in practically any direction. However, to further increase the strength of the union between the box and the frame, vertical reinforcing webs 18, 18 are formed to extend between the bottom framewall 16 andthe inner side wall of the box. These webs are located adj acent to the side Wall 17 and 17, respectively, and serve,

as is obvious, as compression and: tension.

members not only totakestresses longitudinally of the frame and transversely of the box, but also were stresses "tending to ro tatetllfi box in a horizontal plane relative to the frame, whereby any danger of the box being broken, away from. the frame under an O ry ond t ons is p e y: e imi: nated.

portion. and minor details ofconstruction may be resorted to, w.ithout departing from. the spirit of the invention and, scope of the appended. claims.

I claim 1. In combination, a truck frame, and a journal box-formed in one piece with said. tnuck frame, said. j ournalibox. being inclusive. of. a. central portion of. relatively narrow. width and beingenlarged. at its ends to pro-,

vide chambens, to receive an oil obturating ring and an oil elevating paddle, the. frame.

being of a width where joined to the box-to extend; between the enlarged end. portions. of: the box and being joined with the relativelyv narrow central portion of the box.

2 In comblnatlon, a truck frame, and a ournal box formed in one piece. with said truck frame, the frame. being. joined to the.

central portion of the box and thelatterbeing. inclusiveofan enlarged end portion extendingin overlapping relation to an adjacent side portion of the frame.

In testimony whereof I hereunto affix my signature.
